Skeleton Oil Seal describe
 
Skeleton oil seals are the typical example of oil seals. Generally oil seals means skeleton oil seals. The function of oil seals is for insulating the part which need lubrication in transmission parts and outside environment. The lubrication oil can not be permeated. Skeleton just like the steel bar in concrete for gain in strength and keep the shape and tension of oil seals. Oil seals have single lip oil seals and double lip oil seals. The second lip of double lip oil seals can prevent dust, then the dust and impurity can not go inside of machine. Skeleton oil seals also can be divided according to package seal, and seal the exposed skeleton oil seal assembly. According to the working conditions, it can be divided into rotary skeleton oil seal and round-trip skeleton oil seal. Used for crankshaft of gasoline engine, diesel engine, gearbox, differential, shock absorber, engine, axle, etc.
 
 
Features

Oil seals are used for automobile engines and geared motors, and are designed mainly to prevent oil leakage from the end of a rotating shaft, or dust intrusion from the outside air.

Oil seals serve to prevent the leakage not only of lubricants, but also water, chemicals, and gas from "gaps" in machinery. Oil seals also serve to prevent the intrusion of dust, soil and sand from the outside air.
Oil seals are indispensable sealing devices and are used in various fields, including automobiles, aircraft, boats and ships, railroad vehicles, construction machinery, farm machinery, petrochemical plants, and electrical home appliances.
Sealing Element (Rubber)
An oil seal normally consists of three basic components : Sealing Element, Metal Case, and Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts. This is mainly achieved by the sealing element. The materials normally used are Nitrile, Acrylic, Silicone, and Fluorinated Rubber.
Nitrile Rubber (NBR)
NBR is most commonly used material. It has good heat resistance properties, good resistance to oils, salt solutions, hydraulic oils, and gasoline. Operation temperatures are recommended from -40° to 120°C. It also functions well under dry environment, but only for intermittent periods. The disadvantage is poor chemical resistance.
